Disappointed.  I was excited to get these for Thanksgiving but either I received a defective large mixing bowl or the quality is not as advertised.  I only mixed cornbread stuffing in it (gently with a spoon) and the entire bottom is scratched after one use.    I can only imagine how it would look if I had used a metal whisk or handheld mixer.   I have not had this issue with my other All Clad stainless steel.  Wondering if it has to do with the fact these bowls are no longer being made in the US and have less quality control.
